- Under no circumstances touch the battery poles.
- Do not short-circuit the charging lead or charging terminals.
All cables and leads must be secured, undamaged, insulated and adequately dimen-
sioned. Loose connections, scorched, damaged or inadequately dimensioned cables and
leads must be immediately repaired by authorised personnel.
Danger due to ac-
id, gases and va-
pours
Batteries contain acid which is harmful to the eyes and skin. During charging, gases and
vapours are released that may be harmful to health and are highly explosive in certain cir-
cumstances.

9
EN
Only use the charger in well-ventilated areas to prevent the accumulation of explosive gas-
es. Battery rooms are not deemed to be hazardous areas provided that a concentration of
hydrogen of less than 4% can be guaranteed by the use of natural or forced ventilation.
Maintain a distance of at least 0.5 m (19.69 in.) between the battery and charger during the
charging procedure. Possible sources of ignition such as fire and naked flames must be
kept away from the battery.
The battery connection (e.g. charging terminals) must not be disconnected for any reason
during charging.
Do not inhale any of the gases and vapours released under any circumstances - Make sure
the area is well ventilated.
To prevent short circuits, do not place any tools or conductive metals on the battery.
Battery acid must not get into the eyes or onto the skin or clothes. Wear protective goggles
and suitable protective clothing. Rinse any acid splashes thoroughly with clean water and
seek medical advice if necessary.
General informa-
tion regarding the
handling of bat-
teries
- Protect batteries from dirt and mechanical damage.
- Store charged batteries in a cool place. Self discharge is kept to a minimum at approx.
+2 °C (35.6 °F).
- Carry out a visual inspection at least once a week or as often as specified by the bat-
tery manufacturer to ensure that the acid (electrolyte) level in the battery is at the max.
mark.
- If any of the following occur, do not start the device (or stop immediately if already in
use) and have the battery checked by an authorised workshop:
- uneven acid levels and/or high water consumption in individual cells caused by a
possible fault.
- overheating of the battery above 55 °C (131 °F).
Protecting your-
self and others
While the charger is in operation, keep all persons, especially children, out of the working
area. If, however, there are people in the vicinity,
- warn them about all the dangers (hazardous acids and gases, danger from mains and
charging current, etc.),
- provide suitable protective equipment.
Before leaving the work area, ensure that people or property cannot come to any harm in
your absence.
Safety measures
in normal opera-
tion
Chargers with a ground conductor must only be operated on a mains supply with a ground
conductor and a socket with a ground conductor contact. If the charger is operated on a
mains supply without a ground conductor or in a socket without a ground conductor con-
tact, this will be deemed gross negligence. The manufacturer shall not be held liable for
any damage arising from such usage.

10
Only operate the charger in accordance with the degree of protection shown on the rating
plate.
Never operate the charger if there is any evidence of damage.
Arrange for the mains cable to be checked regularly by a qualified electrician to ensure the
ground conductor is functioning properly.
Any safety devices and parts that are not functioning properly or are in imperfect condition
must be repaired by a qualified technician before switching on the charger.
Never bypass or disable protection devices.
After installation, an accessible mains plug is required.

Safety rules - required for USA, Canada and Austral-
ia
General and elec-
trical risks
KEEP THESE INSTRUCTIONS CAREFULLY - This guide contains important safety
and operating instructions for these charger types (for model, see first page of this
document)
Do not expose the charger to rain or snow
The use of accessories not sold or recommended by the charger manufacturer can
lead to fire, electric shock or personal injury
To reduce the risk of damage to plugs and cables, always unplug the charger by pull-
ing at the plug rather than the cable
Only use an extension cable if it is absolutely necessary. The use of an incorrect ex-
tension cable can lead to fire and electric shock. If an extension cable must be used,
make sure that
-the pins of the extension cable plug are of the same number, size and shape as
those of the charger plug
-the extension cable is correctly wired and in good electrical condition
-the cable size is large enough for the AC amperage of the charger, as indicated
above
Do not use the charger with a damaged cable or plug - replace the cable or plug im-
mediately
Do not use the charger if it has been subjected to heavy impact, dropped or otherwise
damaged; hand it over to a qualified service technician
Do not dismantle the charger; hand it over to a qualified service technician if mainte-
nance or repair is required. Incorrect reassembly can result in fire and electric shock
To reduce the risk of an electric shock, unplug the charger from the socket before car-
rying out any maintenance or cleaning. This risk cannot be reduced by setting controls
to the "Off" position
Warning - Risk of
Explosive Gases
It is dangerous to work in close proximity to a lead acid battery. Batteries generate explo-
sive gases during normal battery operation. For this reason it is extremely important to read
this guide before using the charger and to follow the instructions precisely.
To reduce the risk of battery explosion, follow these instructions, the battery manufac-
turer's instructions and those of the manufacturers of any accessories that you plan to
use in the vicinity of the battery. Observe warning signs on these products and on the
engine.
Personal safety
precautions
There must be another person within hearing range of you or close enough to come to your
assistance when you are working in the vicinity of a lead acid battery.
Make sure there is sufficient fresh water and soap nearby in case battery acid comes
into contact with the skin, clothing or eyes
Complete eye protection and protective clothing must be worn. Do not touch your eyes
when working in the vicinity of a lead acid battery

EN
If skin or clothing comes into contact with battery acid, wash the acid immediately with
soap and water. If acid gets into the eye, rinse the eye immediately with running cold
water for at least 10 minutes and seek immediate medical assistance.
NEVER smoke or allow sparks or naked flames close to the battery or engine
Be especially careful to avoid the risk of a metal tool falling onto the battery. This might
create sparks or short-circuit the battery or other electrical components, thereby caus-
ing an explosion.
Remove personal metal objects such as rings, bracelets, necklaces and watches be-
fore working with a lead acid battery. A lead acid battery can cause a short-circuit cur-
rent high enough to melt a ring or similar, thereby leading to a fire.
Use the charger only to charge a LEAD ACID battery. It is not suitable for transferring
power to an electrical low-voltage system other than a starter motor application. Do
not use the charger to charge dry cell batteries, which are used mainly for home ap-
pliances. Such batteries can burst, causing injury to people and damage to property
NEVER charge a frozen battery
Preparing for
charging
If it is necessary to remove the battery before charging, always detach the earth con-
nection first. Make sure all vehicle equipment is switched off to prevent arcing
Ensure that the area around the battery is well-ventilated while the battery is being
charged. The released gas can be effectively dispersed using a piece of cardboard or
other non-metallic object such as a fan
Clean the battery terminals. Be careful to ensure that corrosion residues do not come
into contact with the eyes
Top up each cell with distilled water until the battery acid reaches the level specified
by the manufacturer. This helps to purge surplus gas out of the cells. Do not overfill.
In the case of a battery without cell caps, follow the manufacturer's charging instruc-
tions carefully
Study all battery-manufacturer-specific safety precautions, such as the removal or
non-removal of cells caps during charging and the recommended charging parame-
ters
With the help of the vehicle manual, determine the battery voltage and ensure that it
matches the output of the charger
Charger set-up lo-
cation
Place the charger as far away from the battery as the cables will allow
Never place the charger directly above the battery being charged; battery gases may
corrode and ruin the charger
When measuring acid density or topping up the battery, never allow battery acid to drip
onto the charger
Do not operate the charger in an enclosed area or where there is limited ventilation
Do not place the battery on the charger
Precautions for
DC connection
Only connect or disconnect the DC terminals when all controls on the charger are set
to the "Off" position and the mains cable has been unplugged from the mains. Never
allow the terminals to touch one another
Attach the terminals to the battery and chassis as indicated in points 5 and 6 of the
next section and points 2 and 4 of the section after that
Attach the terminals to the battery poles and turn them to and fro several times to en-
sure a good connection. This will prevent the terminals from slipping off the battery
poles and reduces the risk of sparks.

Steps to follow
with battery in-
stalled in vehicle
Follow these steps if the battery is installed in the vehicle. A spark near to the battery can
cause the battery to explode. To reduce the risk of sparks near the battery:
Arrange AC and DC cables in such a way that they cannot be damaged by bonnets,
doors or moving parts of engines
Keep clear of fan blades, belts, rollers and other parts that pose a risk of personal in-
jury
Check the polarity of the battery terminals. The POSITIVE (POS, P, +) battery pole
usually has a larger diameter than the NEGATIVE (NEG, N, -) pole
Determine which battery pole is connected to the chassis (earthed). If the negative
pole is connected to the chassis (as on most vehicles), go to point 5. If the positive
pole is connected to the chassis, go to point 6
On a negatively earthed vehicle, connect the POSITIVE (RED) charging terminal to
the POSITIVE (POS, P, +) unearthed pole of the battery. Clip the NEGATIVE (BLACK)
charging terminal to the chassis or engine block far away from the battery. Do not at-
tach the terminal to the carburettor, fuel pipes or body panels, but rather to a solid met-
al part of the chassis or engine block
On a positively earthed vehicle, connect the NEGATIVE (BLACK) charging terminal to
the NEGATIVE (NEG, N, -) unearthed pole of the battery. Clip the POSITIVE (RED)
charging terminal to the chassis or engine block far away from the battery. Do not at-
tach the terminal to the carburettor, fuel pipes or body panels, but rather to a solid met-
al part of the chassis or engine block
When disconnecting the charger, switch the controls to the "Off" position, unplug the
mains cable, remove the charging terminal from the chassis and then remove the
charging terminal from the battery
For information about the required charging period, refer to the operating instructions
Steps to follow
with battery out-
side the vehicle
Follow these steps if the battery is located outside the vehicle. A spark near to the battery
can cause the battery to explode. To reduce the risk of sparks near the battery:
Check the polarity of the battery terminals. The POSITIVE (POS, P, +) battery pole
usually has a larger diameter than the NEGATIVE (NEG, N, -) pole
Connect an insulated 6-gauge (AWG) battery cable, not less than 24 inches (609.5
mm) long, to the NEGATIVE (NEG, N, -) battery pole
Connect the POSITIVE (RED) charging terminal to the POSITIVE (POS, P, +) pole of
the battery
Move yourself and the free end of the cable as far away as possible from the battery,
then connect the NEGATIVE (BLACK) charging terminal to the free end of the cable
Do not face the battery when making the last connection
Disconnect the charger in reverse order to the connection process, making the first
disconnection as far away as possible from the battery
A (marine) boat battery must be taken out and charged on dry land. Charging the bat-
tery on board requires special equipment designed for use at sea
Instructions for
connecting the
mains cable in-
cluding earthing
The charger must be earthed to reduce the risk of electric shock. The charger has a mains
cable with integrated earth conductor and an earthed plug.
Connect the plug to a socket that has been installed and earthed in accordance with
all local rules and regulations
DANGER - Never change the supplied mains cable or its plug - if it does not fit the socket,
have a proper socket installed by a qualified electrician. An improper connection may cre-
ate the risk of electric shock.

General information
Principle The main feature of the new Active Inverter Technology is intelligent charging. This means
that the charging behaviour adapts itself automatically to the age and state of charge of the
battery. This innovation extends the battery's service life and reduces the amount of main-
tenance required, while at the same time improving efficiency.
Active Inverter Technology is based on an inverter with active rectification and an intelli-
gent safety cut-out. The charging current and voltage are held constant by a digital control
that is not affected by any fluctuations in the mains voltage.
Device concept The compact design reduces space requirements and makes portable use considerably
easier. In addition to its many existing features, the charger is also of modular design, mak-
ing it perfectly capable of accommodating future requirements. A wide range of options is
available. A 14.4 V voltage limit provides optimum protection for the vehicle electronics.
